Preparation of Fe-Ni/C Composite Catalyst for the Hydrazine Hydrate Catalytic Reduction

Abstract:

Hydrazine hydrate catalytic reduction (HHCR) is a green, eco-friendly method to reduce aromatic nitro compound to aromatic amine. Fe-Ni/C composite catalyst for HHCR was prepared. Preparation conditions of Fe-Ni/C composite catalyst were investigated taking o-chloronitrobenzene’s hydrazine hydrate catalytic reductions as the examples. Experimental results showed that the optimal conditions were as follows: preparation temperature is 50 °C, catalyst carrier is nitric acid treated activated carbon, w(Fe) is 5% and w(Ni) is 0.2%. During the preparation, ultrasonic treatment is also helpful to improve catalytic efficiency of Fe-Ni/C composite catalyst. The newly prepared Fe-Ni/C composite catalyst has combined the advantages of noble metal catalyst and iron-based catalyst and features good reduction selectivity and high catalytic efficiency.
